Welcome to HySelect

Solar Hydrogen via the Hybrid Sulphur Cycle

This European project will demonstrate the production of hydrogen (H₂) by splitting water through the Hybrid Sulphur cycle (HyS) via concentrated solar technologies (CST) with an attractive efficiency and cost. HySelect will introduce, develop and operate a complete H₂ production chain under industrially relevant conditions.


Solar Hydrogen Production

Recent developments and innovations from the consortium partners will be implemented to achieve highly efficient, long-term & cost-competitive concentrated solar energy driven thermochemical hydrogen production.

Energy Source

Concentrated Solar Technology

Use of concentrated solar radiation as a heat source through the solid particle receivers’ technology and in particular the innovative centrifugal receiver CentRec® developed and patented by DLR.


Hybrid Sulphur Cycle

The ambition of HySelect is to close the technical gaps and provide the missing links in the overall, complete HyS cycle technology concept, for a realistic overall evaluation of the technology and its scaleup.

Project Partners

A multi-disciplinary project consortium with experienced project partners from research institutions and industry.

European countries

An international project with partners from Germany, Greece, Finland, Italy and Austria.

Project duration

The project has started at the beginning of 2023 and is planned to finish by the end of 2026.

Overall budget

The project is co-funded by the European Union and supported by the Clean Hydrogen Partnership.

A Research project funded by the European Union and the Clean Hydrogen Partnership

The Clean Hydrogen Joint Undertaking is a collaboration between the European Commission, Hydrogen Europe, and Hydrogen Europe Research. Its objective is to fund research and innovation projects in hydrogen technologies to accelerate the development and optimization of advanced clean hydrogen applications in the EU.
